Microsoft App Center add external package - xamarin.forms

Question

How I do add packages sources in my project?
In my Visual Studio, i go to tools -> options -> Nuget Package Manager -> Package Sources.
And add the package information that in this case is not in Nuget. Now in the App Center I did not find this information and with this my project does not compile

Answer 1

You can create a NuGet.config file as described in the docs.
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<packageSources>
<add key="nuget" value="https://api.nuget.org/v2/index.json" />
<add key="MyGet" value="https://www.myget.org/F/MyUsername/api/v2/index.json" />
<add key="MyAuthNuget" value="https://nuget.example.com/v2/index.json" />
</packageSources>
<activePackageSource>
<add key="All" value="(Aggregate source)" />
</activePackageSource>
<packageSourceCredentials>
<MyAuthNuget>
<add key="Username" value="$USER_VARIABLE" />
<add key="ClearTextPassword" value="$PASSWORD_VARIABLE" />
</MyAuthNuget>
</packageSourceCredentials>
</configuration>

Maybe this will also help somebody. For me the above solution haven't worked. So what I've discovered - always check if official source of packages is same as in your config. For now nuget source have changed to version 3:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<activePackageSource>
<add key="NuGet official package source" value="https://api.nuget.org/v3/index.json" />
</activePackageSource>
</configuration>
